UNITED STATES THOMAS U. PARKER, OF MIFFLINTOWN, PENNSYLVANIA.

IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 123,044, dated January23, 1872.

Specification describing Improvement in Steam Wash-Boilers, invented byTHOMAS U. PARKER, of Mifflintown, in the county of Juniata and State ofPennsylvania.

The invention will first be fully described and then clearly pointed outin the claim.

Figure l is a longitudinal and vertical section, and Fig. 2 a plan viewof my improved steam washboiler.

A is the boiler proper, which is provided with an outlet, a. B is thecover, concaved on top, provided with central inlet b and with verticalflanges b b. O is the frame, for holding clothes, which slopes downwardtoward the sides. having, also, a flat and inwardly curved tube, 0, ateach end, and side-apertured vertical flange c, which rests on thebottom of boiler. O is a subjacentwater-chamber.

The mode of operation is as follows: The clothes being placed on theconvex frame 0, and water being supplied until it is level with the topof flange c, the boiler is placed upon As soon as the water arrives at atemperature of about 212 it generates steam, which accumulates in thedome under clothessupport (3, and, by its elastic pressure, forces thewater up through flat tubes 0 and over the clothes. The water thenpercolates through the clothes, carries the dirt in solution with itthrough apertured flanges a into the subjacent water-chamber C. Thisprocess continues until the water in the bottom of boiler becomes dirtyand discolored, when it is discharged at outlet at. In the meantime thewater in the vessel on top of coverB becomes heated sufficiently to beadmitted and take the place of the dirty water. The process is againrepeated and the soiled water again withdrawn. Another supply of cleanand hot water is then passed through the clothes from the top of coverB, by which the clothes are rinsed and left perfectly bleached andclean.

By my construction of boiler the whole process or series of stepsnecessary in washing is performed without changing the location of theclothes and in the same vessel.

Having thus described all that is necessary to a full understanding ofmy invention, what I esteem to be new, and desire to secure by LettersPatent, is-

The cover B I) 11 b the clothes-frame O o c, and the boiler A a, whencombined, constructed, and arranged as and for the purpose described.
